CAN-HEADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 390,086, datedSeptember 25, 1888.

(No model.)

To all whom it may concern.-

Be it known that I. FRANK M. LEAVITT, a citizen of the United States,residingin Brooklyn, in the county of Kings and State of New York, haveinvented a newand useful Improvement in Oan-HeadingMachines,of which thefollowing is a specification.

My invention relates to machines for applying the heads or ends to thebodies of sheetmetal cans, and more particularly to certain improvementsupon the can-heading machine shown and described in my pendingapplication, Serial No. 247,873, filed August 25, 1887.

My present invention consists in the novel devices and novelcombinations of parts and devices herein shown and described, and moreparticularly pointed out in the claims.

In the accompanying drawings,'which form a part of this specification,and in which similar letters of reference indicate like parts,Figure 1is a side elevation of a machine embodying my invention. Fig. 2 is aplan View. Fig. 3 is a detail section on line 33of Fig. 1. Fig. 4 is asection on line 4 t of Fig. 1. Fig. 5 isa section on line 5 5 of Fig. 1,and Fig. 6' is a vertical section on line 6 6 of Fig. 2.

In said drawings, A represents the frame of the machi-ne,which may be ofany suitable construction.

B is the can-body holding and sizing device, consisting, preferably, oftwo opening and closing semicircular rings or half-molds adapted toclose upon the can body 00 or the end thereof, and hold, true up, andsize the same,so that its outer periphery will correspond to the innerperiphery of the can-head x to be applied thereto by the piston O.

The two half rings or molds B B,which hold the can-body, are, as shownin the drawings, mounted upon a movable carriage or slide, D, whichreciprocates in suitable guideways, D, on the frame of the machine, andthe halfmolds are closed upon the can-body by means of stationary cams bb, against which the halfmolds B B impinge as the slide D advances tobring the half-molds over the end of the canbody. The slide D ispreferably hollow, and within it reciprocates the piston or device 0, bywhich the can-heads are forced upon the 50 can-body. 1

The can-head-supply chute E, as well as the can-body holder B, ismounted upon the slide or carriage D. This supply-chute is provided withone or more movable gates orguards, E,

at its base,just in front of the piston O, to hold 5 the can-heads inposition while the slide D is advancing and until the piston 0 movesforward in the slide D to force the can-head upon the can-body. Theguard or guards E are preferably operated by springs 6 through the bentlevers e, the levers being retracted at the proper moment as the slide Dadvances by in1- pinging against the stop projections e on the guide D.

At the mouth of the halfmolds B B is a ring,b,which is ofslightly largerdiameter than the molds B B when closed, so as to leave an annularrecess or space at the mouth of the mold, equal to the thickness of thecan-head flange, to receive said flange as thecan-head is forced uponthe can-body. This ring I), in fact, constitutes part of the can-holderB as the end of the can-body projects into the same when the can-head isforced upon the can-body by the piston C; but this ring I) need not bemade in two parts, so as to have an opening and closing movement withthe can-holder half-molds B, as the can-holder B and ring b have anendwise movement on the slide or carriage D.

It is therefore preferably made in the form of a continuous or solidring, and is rigidly attached to the slide D. The half-moldsB may beopened by spring 6 The piston O has a thick head, as shown in thedrawings, so that as it moves forward under the can-head chute E toforce one can-head upon a can-body the other can-heads in the chute willbe supported by the piston-head itself. The slide D is reciprocated bycams D which impinge against friction-rollers D on the slide. The pistonO is operated bya cam,

O, which impinges against a friction-roller,

O, on the piston. The piston O is retracted by a spring, 0 F is asupport to bear against the opposite end of the can-body and resist the5 thrust of the piston. All these parts and devices may preferably beconstructed substantially the same as shown and described in my saidformer application, to which and to the patent to be granted thereonreference is hereby made for a more full description.

G is the can-body-supply chute, and H is an intermittently-revolvingcan-bodyfced wheel having receptacles h in its periphery adapted toreceive a single can-body at a time from the chute G and deliver thesame in position ,in front of the reciprocating can-body holder 13 B,and then after the head has been applied to the canbody discharge theheaded can into the dischargechute G. The discharge-chute G is, in fact,but a continuation of the can-body delivery-chute G. The intermediateportion, g, of the chute G G is made curved on a circle concentric withthe ean-body-feed wheel H, and serves as a guard to support and hold thecan-bodies in the feed-wheel.

H is a curved guard extending over the top of the feed-wheel. This guardis continued at H H to form the top wall of the supply-chute anddischarge-chute. The feed-wheel H is given its intermittent motion by anordinary Geneva stop-movement or mechanism, consisting of the slottedwheel h on the shaft h", to which the feed-wheel H is secured, and shafthf, having mutilated disk It and crank h fnrnished with pin or roller h.

The cams which operate the slide D and piston C are secured on thedriving-shaft K, which is furnished with a bevel-gear, in, that mesheswith the bevel-gear kon the countershaft It, and the counter-shaft k isfurnished with a gear, 75, which meshes with a gear, is,

on the shaft h of the Geneva stop-movement,

through which the feed-wheel II is operated.

The machine shown in the drawings is spe cially adapted for putting onthe final heads of filled cans; and for this reason the mechanism ismounted in an inclined position on the frame, and is provided withmechanism for applying only one head at atime. If it is desired to applyboth heads simultaneously, the support F would be omitted and themechanism duplicated at the other end.

I hereby disclaim, as not of my invention, the machines or devices shownand described in Patents Nos. 233,079, of October 12, 1880, to Dillon;294,005, of February 26, 1884, to Norton and Hodgson, and 307,197, ofOctober 2S, 1884, to Jordan.

I claim- 1. In acan'bodyheading machine,the combination, with a can-bodyholding and sizing device havingradially opening and closing parts, of areciprocating slide upon which it is mounted, an independently-inovingpiston or device for forcing the can-head upon the canbody, acan-body-supply chute, and a canbody feed device for automaticallydelivering the can-bodies one by one into position in front of saidbodily-reciprocating can-holder, and means for opening and closing theparts of said holder, substantially as specified.

2. The combination, with a bodily reciproeating opening and closin gcan-holder, adapted to move endwise over the carrbody and to close uponthe same, of a piston reciprocating independently of said holder forapplying the can-head, a can-body-supply chute, and anintermittently-revolving can-body-feed wheel, having pockets orreceptacles to receive the cans one by one, substantially as specified.

3. The combination, with a canbody-sup' ply chute, of anintermittently-revolving canbody-feed wheel above said chute, a devicefor holding the can-body, and a piston for applying the head thereto,said feed-wheel operating in conjunction with said chute to hold thecan-body in position to be received by said can-body holder,substantially as specified.

4. The combination, with a bodilyreciprocating can-holder, of acan'body-supply chute, a caubody-feed wheel jonrnaled above said chuteand operating in conjunction therewith to hold the can-body in positionto be re ceived by said holder, and a piston reciprocating indepemlentlyof said holder, snbstan tiall y as specified.
